The arowana is a truly magnificent fish. Though it seems to glide through the water with much elegance and the least effort, it is capable of moving powerfully, and at lightning speed.
Studies of fossils indicate that the arowana has existed since the Jurassic Age. Having been around for millions of years, this is a very hard species, and individual fish can live for a good half-century!
There are six known species of arowana, also know as dragon fish, in Asia, Australia, Africa and South America. The ones commonly found in local aquarium outlets are juveniles or young adults belonging to the silver, red and gold varieties of the species.
* Arowana fry usually stay in the parent’s mouth for a period of one to two weeks, or until their yolk sacs disappear. Extra care is required in caring for juvenile fish as they are rather fragile during this stage of their lives.
* Gender differences are indiscernible during the juvenile stage and only become apparent when the fish are more mature. The arowana grows very quickly and reaches maturity at around four years of age, when it should measure between 17 to 23 inches.
* Determining the sex of an arowana is not easy, but here are some ways of differentiating the gender. Males usually have a shallower body depth, a longer anal fin, bigger head and mouth, more intense coloring than the females, and are more aggressive in competing for food. The females tend to be slightly larger and broader, especially during the spawning season.
* Young arowanas can be fed food like brine shrimp or bloodworms. The adult fish will eat practically anything that can fit into its mouth!
* Though the arowana prefers live food, it will accept frozen or processed food. Be wary about the kind and source of live feed you use as these may introduce disease or toxins into the aquarium and infect or kill the fish.
* A suitable diet for these carnivores can consist of live food like crickets, centipedes, small frogs, freshwater prawns and the small fish like guppies, supplements like vitamin—enriched krill, and pellet and flake food.
* It is important to give them a well-balanced diet—too much fat in their diet could cause health problems like “bulging eye”, a condition in which one of the fish’s eyes points downwards.
Arowana is a type of fish many new fish hobbyists dream to have but never dare rear them let alone keep them as pets. I understand the resistance. It may look very intimating at first especially of its heavy price tag, but believe you me it’s worth the effort and pleasure of keeping them.
